Relative expression of stress-related genes during acclimation at low temperature of psychrotrophic Oenococcus oeni strains from Patagonian wine.

In the present study, we evaluated the transcriptional response of four stress-related genes in three Oenococcus oeni strains after acclimation at two different temperatures. Gene expression was analyzed at time zero and after 48 h acclimation at 18 and 21 °C. After the acclimation period cells were inoculated into sterile Pinot noir wine and MLF was followed for 25 days to investigate if different acclimation temperatures could influence cell survival and MLF performance.

Genome Sequence of Oenococcus oeni UNQOe19, the First Fully Assembled Genome Sequence of a Patagonian Psychrotrophic Oenological Strain.

Oenococcus oeni UNQOe19 is a native strain isolated from a Patagonian pinot noir wine undergoing spontaneous malolactic fermentation. Here, we present the 1.83-Mb genome sequence of O.
